9 Claims.

My invention relates to sanitary attachment linings for bath-tubs,wash-basins and like containers, and it has for its object to provide animproved device of the character indicated.

It is also an object of this invention to provide a. strong, durable andeflicient attachment lining of the character indicated which can befolded or otherwise collapsed into a small bundle so that it may beconveniently stored or transported; which may be quickly, and securelyfastened in operative position within a bath-tub or other container sothat removed after use; which will be of comparatively inexpensiveconstruction, and which, in. its best form, will provide aninconspicuous lining having a hard, non-fibrous, sanitary andattractively smooth glossy inner surface.

To these ends I have provided a lining attachment of the characterdescribed having the peculiar features of construction and operation setforth in the following description, the several novel features of theinvention being separately pointed out and defined in the claims at theclose thereof. 7

In the accompanying drawing':- Figurelisatopplanviewofaliningforabath-tub, said lining being constructed in accordance with my invention.

Figure 2 is a longitudinalsectional view of a bath-tub provided with afining like that of Fig. 1. Figure 3 is an enlarged sectional view ofone "end portion of the lining illustrated in Figs. 1

and 2.

Figure 4 is of Fig. 3.

Figure 5 is a detail hereinafter referred to. The embodiment of myinvention herein illustrated is a complete, self contained liningstructure for a bath-tub, said structure comprising a vessel-likecontainer of thin flexible sheet material that is indicated generally atand which is of a size and shape to fit and coverthe interior portionthereof. The vessel-like container 10 is constructed with a bottom 12 tofit against the bottom of the tub; with oppositely disposed side walls13 and 14 to fit against the opposite side walls of the tub, and withoppositely disposed endwalls 15 and 16 to fit against the end walls ofthe tub.

The bottom wall 12 is made, wall 15, with an an enlarged section on line4-4 adjacent to the end outlet aperture 1'1 that is normally closed by acover or closure element 18 of thin flexible sheet material adhesivelyand lyfastenedtothetopsideofwall 12in position to cover and closureelement 18 is made at one side thereof that is farthest from the endwall 15 with an integral tang extension .19 which extends upwardly fromsaid closure element to the upper it may be quickly detached and I of abath-tub 11, particularly the lower closetheoutlet 1'1. This.

portion of end wall 15 where it is cemented or otherwise fastened to theinner side of said wall as at 20.

The outlet 1'! in bottom wall 12 is located so that when the lining isin position within the tub 11 said outlet is in register with the usualoutlet 21 of the tub.

It is a feature of this invention that the exterior of the vessel-likelining is adhesively engaged with the surface of the tub so thatit willbe maintained in extended vessel-like shape while in use. Thisengagement may be established by the employment in any suitable mannerof an adhesive or cement. I

In the best form of my invention however. I provide a plurality ofadhesive plaster patches 22 each of which consists of a small piece oftextile fabric 23 having a coating of adhesive 24. In practice I haveemployed patches 22 made from ordinary surgeons adhesive plastercomprising a textile fabric body 23 coated upon one side with awaterproof adhesive composition 24-including rubber, pitch, and gums, asusual, and which will adhere strongly to any surface without setting orcuring so that it can be quickly and cleanly removed or strippedfromsaid surface y when desired.

Each patch 22 is permanently mounted upon the inside of the vessel-likelining 10 opposite, or in register with, an aperture 25 formed in thelining.

Each aperture 25 is of non-angular, or circular, shape and is locatedwithin the top marginal portion of the lining adjacent to the chime orupper edge thereof. The several apertures 25 are located at intervalsthroughout the circuit of the lining and as will layer of each patch isexposed upon the exterior of the lining by its aperture 25. The area ofthe aperture 25 -is substantially less than tlie area of that portion ofthe patch which is adhesively' engaged with the wall of the lining sothat the latter portion materially reinforces the lining materialimmediately adjacent to and surrounding the aperture.

These exposed portions of adhesive material may adhere to other portionsof the lining while the latter is collapsed in the form of a bundle orpackage while in storage or transit but may be readily disengaged whenthe lining is opened up for use.

When the liningistobe useditis opened and placed within the tub so thatits bottom rests on the bottom of the tub and its upright walls areagainst the walls of the tub. Then by applying fingerpressuretothemiddleof eachpatchthe adhesive of the latter is shoved into its aperture 25and against the proximate wall of the tub to which itAfterusingthetubewiththelininginposimovements of tion therein the batherpulls upwardly upon the tang extension 19 and strips the closure element18 off from the bottom 12 whereupon the contents of the tub and liningdischarge by gravity through the outlets 17 and 21 after which thelining is stripped fromthe walls of the tub and removed.

The embodiment of my invention herein illustrated has its end wall 16constructed at its top with an apron extension 26 made near itsextremity with apertures 27 and provided with patches 28 attached to thetop surface of the extension, each opposite one of said apertures. Bymeans of these patches- 28 the upper end of the extension 26 isadhesively attached to the top of the tub to hold the end wall 16against being displaced downwardly through movement of the bathers bodyagainst the same.

It is an important feature of my invention that the; vessel-like liningattachment herein illustrated, with the exception of the adhesivepatches 22 and 28, is made from a thin cellulose material such as thatwhich is known commercially as cellophane. This cellulose material is ofgreat tensile strength; it is nonfibrous; it has a desirably hard,smooth glossy surface, and may be colorless and transparent so that itis not conspicuous.

An advantage to the use of this material is that the lining is noteasily displaced through the body of the bather while the latter iswithin the tub. Another advantage is that after use, and before removalof the lining the latter may, if desired, be quickly cleaned by rinsingor flushing so that, if desired, it may be used more than once althoughlow cost of production permits of discarding the same after one use andfor sanitary reasons this may be done., Its use will prevent the spreadof disease in hotels and other public places where the bath tubs andwash basins are used by many diiferent people.

My new lining attachment may be produced in various sizes and shapesappropriate to the bathing container in connection with which they areto be used and therefore the invention is notlimited to the particularembodiment herein shown.

Also the vessel-like structure of the attachment may be made from asingle piece of sheet material or from two or more pieces fastened tovgether.

What I claim is:

1. A lining attachment of the class described consisting of a'vessel-like structureof thin flexible sheet material adapted to befitted within a container, said structure comprising normally adhesivewaterproof means for adhesively and separately fastening theupperportion thereof to said container.

2. A lining attachment of the class-described consisting of avessel-like structure of thin flexible cellulose sheet'material adaptedto be fitted within a container, said structure comprising normallyadhesive waterproof means for adhesively fastening the upper portionthereof to said cont'ainer.

4. A lining attachment of the character described constructed inaccordance with claim 3 having a bottom wall made with an outlet andalso including a closure element ofthin flexible sheet material coveringsaid outlet upon the inner side of said bottom wall and adhesivelysecured to the latter, said element being made with a tang extension bymeans of which it is manipulated to open said outlet.
